Ok, everyone has read the latest issue of Sport Aviation (April issue) by now and has seen the Turbo RV-4 on the cover. I hit the ATP Website and am... well, quite intrigued to say the least.
Could someone please nutshell for me how a turboprop works. Then, after the nutshell overview go into some detail?
I understand it is an oil burner like the one in the basement, but that is about it.
In the article it says the exhaust stack is too short and causes aerodynamic back pressure limiting it's performance and raising EGT readings. Why can't they leave the short stack and use a venturi tube to aid in gas extraction from the stack at higher speeds? I am just an idiot with probably an overly simplistic idea, but I am interested in the concept to say the least.
